Its hard to tell what kind of bug that is. I can't find that error string anywhere in the MODX core or assets directories, or in the Articles code, so it may be JS bug reported by modExt.
Could you report it here?

Quote from: gelstudios at Sep 20, 2013, 03:44 AMGetting an error when making or editing an article
"Cannot set property 'Tags' of undefined"
The TV Tag is there an unedited, modx 2.2.9 and articles 1.7.2 (All up to date)
This is preventing the RTE from loading and becoming a realllll pain.
Nothings showing in the error log either 
Any help would be greatly appreciated, thanks!
Do you mean you can't set Tags in Articles because i'm having the same issue.
I've upgraded to 2.2.9 and Articles 1.7.2 and the Tags dropdown now doesn't display anything so I can neither choose or add any tags.

This sounds like it could be a caching issue. Have you tried clearing the browser cache?

Well It is now working but just not as it used to be where I was able to choose from a list of tags already in use. I cleared the cache a couple of times and i can now add tags.
Thanks.
